I think it was dead level and could have gone either way on the cards tonight. However, I think Booth would win a rematch more comfortably judging by the pattern of tonights fight. Booth knows he can get to him later in the fight now, he'd put the pressure on even more intensely earlier on.
Ed Robinson just said 2 of the judges had Booth ahead (I think) edit; Nope it was Marsh who was ahead
So yeah, like I said it would have been dead level at the end. Let's be honest Booth was winning 11 and would have in all likelihood won the last such was his momentum in the fight and Marsh tiring.
